Standards for clearance from gas pipes during construction. Criteria for the location of gas pipes in the kitchen: installation rules in an apartment and private house, regulatory requirements. Features of the security zone of high pressure gas pipelines

Why were norms for the distance to buildings and objects from gas pipe? Alas, we often neglect the norms of SNIP, especially on household plots and summer cottages. A particularly disdainful attitude towards the norms is if the threat of a fine is unlikely. But is it the fine?

The standards that specify the distance from the gas pipe are for our safety. Non-compliance or insufficient compliance can result in something worse than penalties. So is life really worth neglecting these indicators, even if it’s not entirely convenient?

Modern standards are suitable for the design of new gas supply systems, as well as the modernization of existing ones. Along them are the main gas outlets for household use do not exceed a pressure of 1.6 MPa. According to the same standards, gas supply is designed in dacha and cottage villages.

These standards are not suitable for gas supply systems of industrial organizations, for example, oil refining companies, ferrous metallurgy and others.

Composition of the gas supply system:

• external pipelines;
• internal;
• equipment and units for control, measurement, gas supply, and system maintenance.

Position

So, let's talk about system design and the distance of system pipes from various objects.

To do this, let us clarify that, according to SNIP, there are two types of gas pipelines:

• underground;
• outer.

Each type has its own distance standards; let’s consider them in more detail.

Underground

The distance from the house to the gas pipe in the embankment cannot be less than 5 m. There are special provisions of SNIP, according to which the distance can be reduced by 50%, however, they are regulated by the characteristics of the terrain and the passage of the gas pipeline. For example, laying pipes between houses, arches, in very limited areas, etc.

The distance to the gas pipe from the outer walls of the well, chambers or other equipment of utility networks should not be less than 30 cm. Laying must be carried out in accordance with technical requirements and conditions. Only this can be a guarantee of safety. By the way, this is why independent transfer or organization of the gas supply system is not allowed.

The distance to overhead communication lines, as well as electrical external networks, cannot be less than 2 meters. The same applies to the gap between the gas pipeline and heat transfer channels. The distance from the gas pipe to the fence, taking into account the underground laying of the pipeline in villages, must be at least 50 meters. SNIP provides for a reduction in the gap, but only if certain standards prescribed in the regulations are taken into account.

The depth of laying the gas pipeline must exceed 0.8 m for highways and roads with heavy passenger traffic and 0.6 m for roads with low traffic.

Ground and above ground

Overhead wires are laid along the facades of buildings, on special supports made of materials that do not burn.

The laying location depends on the pressure of the gas pipeline:

• up to 0.6 MPa – wiring is allowed on shelves and overpasses, as well as columns, supports and along the walls of buildings industrial applications;
• up to 0.3 MPa - it is allowed to lay on the walls of residential buildings and public buildings of at least the 3rd degree of fire resistance.

It is prohibited to lay gas pipelines of any pressure for the purpose of gas transit, according to SNIP:

• along the walls of kindergartens and schools, hospitals and companies that involve large crowds of people;
• for buildings in which the walls consist of panels and have metal cladding with polymer insulation;
• for buildings of categories “A” and “B”.

Medium and high pressure gas pipelines are prohibited from running along the walls of residential buildings. It is also forbidden to run a transit gas pipeline through window openings.

In areas near the ground, pipes must be enclosed in a special case. The horizontal distance to the gas pipe from the ground cannot be less than 35 cm.

The distance from the gas pipe to the chimney must be more than 2 meters outside and not less than a meter inside building. However, this indicator depends on many factors, for example, location, gas supply conditions and pipe configuration, etc.

In room

It is very important to comply with the technical conditions in the room, since it is often caused by emergency situations with gas is precisely household non-compliance with standards. In most cases, polyethylene gas pipes are used in apartments and private houses. Usually they go exclusively to a gas stove or oven. But in some houses there is an autonomous gas heating. And here a special boiler is already used.

In this case, the floor from the pipe must be at a distance of at least 50 cm. The same distance is from the wall to the boiler. The vertical distance to the chimney should not be less than 80 cm inside. The distance of the pipe to the cooking stove is the same. Distance from pipe to socket in small room should not be less than 30 cm.

To secure a building means to secure life. That is why it is important to comply with the rules and regulations specified in SNIP.

at pressures up to 0.3 MPa inclusive, pulling polyethylene pipes in the gas pipeline with a safety factor of at least 2.5 without welded joints or connected using parts with a seal, or connected by butt welding using welding equipment high degree of automation;

at a pressure from 0.3 to 0.6 MPa inclusive, stretching polyethylene pipes in a gas pipeline without welded joints or connected using parts with welded joints or butt welding using highly automated welding equipment with a safety factor for gas pipelines in settlements of at least 2, 8, and outside settlements – at least 2.5. The space between the polyethylene pipe and the worn-out steel gas pipeline (frame) along its entire length must be filled with sealing (sealing) material (cement-sand mortar, foam material);

at a pressure of up to 1.2 MPa, cleaned cladding (using Phoenix technology) inner surface gas pipelines using a synthetic fabric hose on a special two-component adhesive, subject to confirmation in the prescribed manner of their suitability for these purposes at specified pressure or in accordance with standards ( technical specifications); the scope of which extends to this pressure.

5.7.2 Restoration of worn-out steel gas pipelines is carried out without changing the pressure, with an increase or decrease in pressure compared to the existing gas pipeline.

In this case, it is allowed to save:

intersections of restored areas with underground utilities without installing additional casings;

depth of installation of restored gas pipelines;

distances from the restored gas pipeline to buildings, structures and engineering communications according to its actual location, if the pressure of the restored gas pipeline does not change or when the pressure of the restored gas pipeline increases to 0.3 MPa.

Restoring worn-out steel gas pipelines with increasing pressure to high is permitted if the distances to buildings, structures and utilities meet the requirements for a high-pressure gas pipeline.

5.7.3 The ratio of the sizes of polyethylene and steel pipes during reconstruction by the pulling method should be selected based on the possibility of free passage of polyethylene pipes and parts inside steel ones and ensuring the integrity of polyethylene pipes. The ends of the reconstructed sections between the polyethylene and steel pipes must be compacted.

At what distance from the fence and other buildings? high voltage line power transmission and other communications, it is possible to build a home - an issue that requires a priority solution. Failure to comply with standards leads to legal conflicts with neighbors. To avoid such problems, you should familiarize yourself in advance with the legal requirements regarding the placement of residential buildings.

The wall of the house can coincide with the line of the external fence

Fundamentals of legal regulation of the placement of buildings

No one normative act does not precisely regulate the issue of distance between buildings. The norms for the position of architectural structures on the site are determined by the local administration. To avoid paying a fine and demolition of the building, you need to contact the architecture committee to familiarize yourself with the accepted standards for the placement of buildings in a given locality.

The issue of planning buildings is regulated by the following standards:

1. SP 30-102-99. Establishes norms for distances between individual housing construction objects and other extensions. Thus, a residential building must be located at a distance of no less than 6 m from dwellings, garages and outbuildings on the neighboring site.
2. SP 4.13130.2009. The main document establishing fire safety measures. Maintaining safety distances between buildings is intended to protect buildings from fire and prevent the spread of fire due to their close proximity.
3. SNiP 30-02-97. Regulates the placement of buildings in gardening associations. IN in some cases, by decision of the local administration, the standard applies to individual housing construction, private plots and summer cottages.
4. SNiP 2.07.01-89. Regulates the area related to the general development of a populated area. Unlike previous standards, this regulatory act regulates the placement of buildings on a site from the point of view of local authorities, and not the owner.

Permissible distances between houses on adjacent plots

The distances between dwellings in neighboring areas differ in different regions. Take into account the location of the site (in the city or rural areas). The distance is calculated based on the position of the extreme points of the building - balcony, terrace and porch. If the dwelling is connected to a garage close to the neighboring plot, the distance is determined relative to its edge.

Table of minimum distances according to fire safety standards between houses from different materials

The amount of indentation depends on the type of cladding. The following groups of coatings are used for wall cladding:

1. Non-combustible materials - stone and reinforced concrete. The safest types of cladding, characterized by a low susceptibility to fire. Stone buildings can be located at a distance of at least 6 m from each other. Are the best option for construction on small plots, allowing you to build houses near fences.
2. Combustible materials – lumber. To avoid a large fire, the distance between wooden buildings must be at least 15 m.

The issue of placing houses in the construction of which several materials were used is being addressed separately. Dwellings with stone walls, But wooden floors, should be placed at a distance of at least 8 m from each other. The same distance is maintained if structures in neighboring areas are built from different groups of materials.

Limiting the distance from the wall of the house to the fence and neighboring buildings

By general rules The distance from the dwelling to the fence according to SNiP must be at least 3 m, and between neighboring houses - at least 6 m. A small, less than a meter, setback of the dwelling from the border of the site is a violation. If a neighbor built his house a meter from the fence, you can safely go to court, even when the normative distance between dwellings is observed.

Minimum distances of objects and buildings to the neighbor’s fence

When planning the future use of the site, it is recommended to draw a diagram of it. The land should be divided into zones, in one of which a residential building will be built, and in the others - a garage and other necessary extensions. According to GOST, buildings must be removed from the fence and the house at the following intervals (m):

• at least 1 – outbuildings for storing equipment;
• 6 – from the windows of a neighbor’s house;
• at least 12 – premises for housing livestock;
• 6 – summer shower;
• 8 – toilet and compost pit.

Particular attention is paid to the location of the bathhouse. Smoke from a sauna chimney located close to neighbor's house, is the cause of quarrels with neighbors who may legally demand the demolition of the building.

To avoid troubles when building a bathhouse, adhere to the following distances:

• at least 12 m from neighboring structures - for smoky steam rooms;
• more than 6 m from the fence and the house, at least 4 m from the buildings located on the site - for a sauna;
• at least 12 m from the neighbor’s bathhouse and other wooden buildings.

The garden plot is also subject to zoning. It is necessary to plan the land so that it can be used to build living quarters and the necessary outbuildings. Architectural structures located on the SNT site are erected at a distance of (m) from its boundaries:

• 4 – greenhouse, pen for birds and livestock;
• 1 – buildings for storing equipment;
• 8 – bathhouse, toilet and shower.

It is better to discuss the short distance between the house and the neighbor’s fence with the neighbors

If you want to build a septic tank on your property, it is recommended to obtain the consent of your neighbors. Despite the fact that for the construction treatment system permission is required only from the local sanitary and epidemiological service; preliminary discussion and written consent for construction will protect owners from false complaints about “flooding of the soil and bad smell"from unscrupulous neighbors.

Coordination of the design of the treatment system allows you to avoid situations where a septic tank is mistakenly built close, literally a meter from the drinking water well.

The purifier is placed at a distance of at least 5 m from the home and 3 m from the boundaries of the site. The system should not be located far from a residential building, as this often leads to blockages.

Distance from the house to the object outside the fence

When deciding on the placement of a house on a site, they also take into account the distance of the future building to power lines, gas pipelines, railway and cemeteries. This will protect households from traffic noise and fumes from burial sites, and avoid flooding and subsidence of a private building located on excessively wet soil.

Before power lines

To protect the population from damage electric shock Due to accidental deformation of wires, security zones are established on both sides of power lines. Within these areas, housing construction and the construction of dacha and gardening partnerships are prohibited. If a house does end up within the power line, it is not demolished, but a ban on reconstruction and capital construction is imposed.

The minimum distance from the house to the power line depends on its voltage

Compliance with power line protection zones also ensures the safety of the site electrical network from vibrations that occur during the construction of a house. The safe distance from the fence to power lines is determined based on the voltage level and is:

• 35 kV – 15 m;
• 110 kV – 20 m;
• 220 kV – 25 m;
• 500 kV – 30 m;
• 750 kV – 40 m;
• 1150 kV – 55 m.

To the pond

When dreaming of a house near a river or pond, you need to determine whether the purchased plot is included in a water protection zone - land adjacent to a water body with special legal protection. The establishment of a special regime is aimed at preventing pollution, siltation and salinization of the soil, preserving the richness of waters and maintaining the natural biocenosis.

The minimum distance from the house to the river depends on the type of reservoir

Building a house near a pond also carries the risk of its destruction due to its placement on softened soil. When laying the foundation, the width of the water protection zone of a river or sea is taken into account. This territory is determined by the length of the reservoir and is:

• 10 km – 50 m;
• up to 50 km – 100 m;
• over 50 km – 200 m;
• for the sea - more than 500 m.

To the gas pipe

If there is an external gas pipeline on the site, the distance between it and the house must be at least 2 m. The safety distance for underground pipes is determined based on the gas supply pressure. Within populated areas, as a rule, the pressure in the gas pipeline does not exceed 0.005 MPa. In this case, the foundation is laid at a distance no closer than 2 m from the gas pipe.

In the village, a distance of 2 m is sufficient to the low-pressure gas pipe

To the road

In different settlements, the distance between the fence and the road varies. In small villages, as a rule, this figure should be at least 3 m. If the local administration has allowed to deviate from the standards, it is still better to build a fence away from the passage. This will not only protect residents, but also make it easier to access the site.

It is better to stay away from the dust and smells of the road: at least five meters from the fence

When talking about the distance between the fence and the road, the concepts of “road” and “roadway” are distinguished. The first is called a canvas with a pedestrian zone and a curb, optimal distance to which is about 3 m. An area for movement is considered for the second Vehicle. If land plot located near highways, the distance to the fence should be at least 5 m.

The norm for the distance from a cemetery with an area of ​​more than 20 hectares to a residential building is at least 500 m. If the site is located in a village near a small cemetery, the dwelling should be located at least 300 m away from it. For columbariums, memorial complexes, closed burial places, the permissible the distance to the home is 50 m.

The minimum distance to the cemetery is determined by its size

To the railway

The noise and smell from the railway will not please anyone: we are building a house no closer than 100 m

To protect land owners from train noise, the distance from the private sector to the railway must exceed 100 m. If the railway track is located in a depression, or the carrier company has taken measures to ensure noise protection (installed noise barriers, fences), it is permissible to build a house near the tracks, but not closer than 50 m.

Hello, dear readers. If there is a gas pipe in the kitchen, special standards apply to it. These are distances from surfaces and from household appliances. Proper installation of gas pipes throughout the apartment is also important.

Apartment standards

The gas pipeline is installed in the apartment according to a previously developed plan. But even before this, it is necessary to determine the operating conditions of the gas pipeline. So, if gas pmi 2013 units operate in the kitchen, it will be suitable for them mandatory element. Its presence in the boiler room is the key to warmth throughout the house.

For the positions of the gas pipe in the kitchen and apartment, the standards are as follows:

1. No installation in residential areas or ventilation shafts.
2. Intersection with openings for windows and doors is unacceptable.
3. Laying in hard-to-reach areas is prohibited. For example, behind designer decoration on the wall. Gas equipment must be provided with quick and easy access in case of malfunctions.
4. The minimum distance of the gas pipe from the floor is 2 m.
5. When using thin-walled pipes, the length of flexible communication components should not exceed 3 m. Great importance has also the density of connections of network elements.
6. Installation is permitted only in those rooms where the minimum ceiling height is 220 cm. And these rooms must be well ventilated.
7. The kitchen should not be provided with ventilation affecting the living areas.
8. Wall and ceiling surfaces, close to gas equipment, must have special coating made of non-combustible plaster. If there is no such coating on the wall, it must be insulated from gas appliances using metal sheet. Its suitable density is 3 mm.

Question about a private house

To lay in a private house, you also need to know the standards. To begin with, gasification here begins with notifying the local gas organization and planned works. It provides a technological condition that determines the algorithm for constructing a gas pipeline. Settlement in progress technical issue. A personal development for gasification of a certain area is created. Also, a warrant for the installation of a gas pipeline is issued by the traffic police.

If neighboring houses are already provided with gas, you only need to connect the pipes in a specific area to the main network. The working pressure factor is also important here. Its parameter in the main pipes determines the choice of pipes to pass into the house.

The preferred gas source determines the gas supply technology: centralized or autonomous.

Gas pipelines can also run to private homes underground or above it.

And the standards for installing pipes in the kitchen are: a private house identical to the points in the housing issue.

Installation standards

The rules and regulations for installing a gas pipe in the kitchen are as follows:

1. Before work, close the main valve.
2. The gas pipeline is purged if the pipe is moved.
3. The pipe is secured to the wall. These are special clamps and brackets.

The type of fastener is determined by the length and diameter of the pipes.

1. If there are electrical cables near the pipes, then the minimum distance here should reach 25 cm. A gas technology is removed from the electrical panel by 50 cm.
2. Location near cooling equipment is unacceptable. In this matter, owners often make mistakes. Is it possible to place a refrigerator near a gas pipe? It is forbidden. So the refrigerator radiator can quickly overheat, and the device itself will become faulty.
3. The minimum distance from the gas pipe to the stove is formed as follows: the branch to it goes only along the line of the connecting fitting. The shut-off valve is placed 150 cm from the floor and 20 cm from the side of the stove. The cash advance businesses plate is installed using a heat-resistant flexible hose.
4. Work should be carried out in a room with stable ventilation and natural light.
5. The minimum ceiling height is 220 cm.
6. The slab and the opposite wall must be separated by at least 100 cm.
7. The surfaces around the pipes and slabs are covered with fire-resistant material - plaster.
8. The pipes are routed so that the slab is 7-8 cm from the walls.
9. The stove is used only in a kitchen that has a fence from the corridor: a wall or partition and a door.
10. The height of the gas pipe from the floor is at least 2 m.

Another important aspect is maximum length certified gas hoses. In Russia it has no restrictions. In Europe it is 2 m. We can have products from 2 to payday loans gallatin tn 10 m and more. It all depends on the owners’ tasks and working conditions.

Transfer Aspects

When a gas pipe is in the way in the kitchen, it can be moved or disguised. In the first case, you must strictly observe regulatory requirements moving a gas pipe in the kitchen.

The same installation criteria are followed here:

The maximum length of flexible elements is 3 m.

The norm for a gas pipe in the kitchen in height from the floor is 2 m (minimum).

The connection areas must be rigid.

The pipeline itself should be painted.

The areas where the system intersects with the walls are “packed” - a special case is used.

When working on a gas transfer network, block the gas before working.

You need to decide on your tasks. It is better to designate them schematically and show them to specialists.

And the decision to cut or move a pipe in the kitchen is the prerogative of special services. The owner can only indicate his plan. And the masters can approve or prohibit it. They will tell you what the price of such an update is, where it is better to start with financial assistance grants and who to contact.

The algorithm of actions in solving these problems is as follows:

1. Contacting the gas company at the registration area. Create a statement about the desired changes.
2. Based on the application, specialists arrive. They inspect the conditions, carry out checks and make the necessary calculations so as not to violate the norms for the location of the gas pipe in the kitchen.
3. Creating an estimate. When ready plan ends up in the hands of the customer, other formalities are settled, the customer pays for the service. If necessary, the plan is modified.

If the work according to the customer’s scenario is not safe, or the estimate does not suit him, he can disguise the pipe. For example, purchase a special elegant box

If there are no dilemmas with the estimate, then within 5 days of its approval, craftsmen arrive to the customer. Before their visit, the client can:

1. Contact them and find out if they need anything consumables and immediately resolve this issue,
2. Clear the area for dismantling old products and installing new ones. Workers should not have problems accessing the network.
3. Protect all valuables, kitchen appliances and surfaces. A tarpaulin or tarpaulin is used for protection. similar materials. After all, the work ahead is very dusty.
4. The valve is blocked. Gas should not flow to the pipes during this period. It is easier to connect components using a siphon connection.

The work itself goes like this:

1. To remove residual gas and debris, the pipes are purged (after the gas is blocked).
2. The unnecessary component of the system is removed.
3. The resulting hole is plugged.
4. A hole is made at the location where the new element is installed.
5. The new structure and other elements are welded here, if they are included in the project.
6. The crane is being installed. The connecting areas are sealed with tow.
7. The stove is connected. The standard is observed at what distance from the gas pipe the stove can be placed. This aspect has already been discussed here (the tap is at the level of the connecting fitting, the minimum distance from the side of the slab is 20 cm). With the upper variation of the fixed annuity interest rate wiring, the shut-off valve is placed at the lower end of the gas apparatus. Distance from the floor: 150-160 cm. The gas riser is at least 20 cm away from the tap.
8. A work completion certificate is generated and signed.

The question of camouflage

Is it possible to hide a gas pipe when there is no way to move it? It is possible and necessary. Special boxes are available for sale.

You can come up with your own plan on how to hide the gas pipe, and at the same time the counter in the kitchen.

If you have absolutely no idea how to do this effectively and harmoniously, look at the photo “How to hide gas pipes in the kitchen?”

Conclusion

It is necessary to install gas pipes in the apartment and in particular in the kitchen in accordance with current regulations. This is both compliance with the law and a guarantee of your safety.
